Shimazaki | October 1, 1991 |
A vibration absorbing mechanism for a compressor in an automotive air conditioning system is disclosed which comprises a mass which includes a first penetration hole; first and second bushings, each of said bushings including an inner cylinder which is provided with a second penetration hole, an outer cylinder and an elastic member which is disposed and compressed between the outer surface of the inner cylinder and the inner surface of the outer cylinder; and a screw bolt. The first and second bushings are disposed at both ends of the mass to align the first penetration hole with the second penetration holes. The screw bolt passes through the first penetration hole and each of the second penetration holes and then is fastened by a nut. According to the above mechanism, vibration which the compressor receives from an engine through a mounting bracket can be reduced. Therefore, durability and silentness of the compressor also can be improved.
